Mathematical Modelling and Calculation of Suitable Robot Trajectory in Composite Frame Manufacturing

Popis výsledku v původním jazyce

This chapter deals with the production process of a specific composite frame types. The technology of a carbon (or a glass) filament roving winding on a non-bearing frame in 3D is described with a varying shape and circular cross-section. If the frame cross-section is not circular, an imaginary cylindrical “envelope” (with minimum possible radius) is considered and stretched on the frame surface. In general, composites often replace traditional materials such as steel, iron, wood, etc. The most important advantages of composites are their high strength, flexibility, light weight (this often allows a significant reduction in the weight of industrial constructions), long life and minimum maintenance requirements. The composites offer an attractive ratio of material properties-to-production costs. Traditional procedures of composite manufacturing based on manual skills of technicians are labour-intensive and time-consuming. Composites thus become a fully–fledged material in design engineering applications. Moreover, the conventional techniques do not ensure accurate fibre winding on the frame. One of the possible approaches to producing composites is to stretch the fabric from the fibres on a frame with an arbitrary geometry. However, if the frame of the composite is a open/closed 3D frame or a frame with a more complicated 3D shape (e.g., see Figure 1a) or several layers of the fibre strands are wound simultaneously on the frame, then this approach is not suitable. In such cases, the method of winding of endless fibre strands on a frame geometry using rotary fibre-processing head is preferably used. The use of industrial robots in composite production greatly reduces production costs, production time and minimizes scrap rate. This method provides full control over the placement, laying direction, and the amount of fibres on the frame as well as the homogeneity of the structure. The final composite is obtained after dry winding of the required layers of strands on the frame, then inserting the composite into the mould and injection of the resin to the mould and by using subsequent heating and pressure on the product. The composite manufacturer achieves the desired mechanical properties by suitably choosing the material of the frame and the wound fibres. Keeping the correct angles of windings of fibres and uniformity of the individual layers of the wound frame is important during production of the composite. This article is focused on the process of precise winding of fibres on the frame. The process for producing composites with polyurethane frame by method of dry winding on a frame is described. The manufacturing process at experimental laboratory is described. The key equipment of experimental laboratory is an industrial robot KR 16-2 and fibre-processing head.
